Description Onuralp SEZER 2010-05-11 11:09:26 EDT
Summary:

SELinux is preventing /opt/teamviewer/teamviewer/5/wine/bin/wine-preloader from
loading /opt/teamviewer/teamviewer/5/wine/drive_c/Program
Files/TeamViewer/Version5/TeamViewer.exe which requires text relocation.

Detailed Description:

The TeamViewer.exe application attempted to load
/opt/teamviewer/teamviewer/5/wine/drive_c/Program
Files/TeamViewer/Version5/TeamViewer.exe which requires text relocation. This is
a potential security problem. Most libraries do not need this permission.
Libraries are sometimes coded incorrectly and request this permission. The
SELinux Memory Protection Tests
(http://people.redhat.com/drepper/selinux-mem.html) web page explains how to
remove this requirement. You can configure SELinux temporarily to allow
/opt/teamviewer/teamviewer/5/wine/drive_c/Program
Files/TeamViewer/Version5/TeamViewer.exe to use relocation as a workaround,
until the library is fixed. Please file a bug report.

Allowing Access:

If you trust /opt/teamviewer/teamviewer/5/wine/drive_c/Program
Files/TeamViewer/Version5/TeamViewer.exe to run correctly, you can change the
file context to textrel_shlib_t. "chcon -t textrel_shlib_t
'/opt/teamviewer/teamviewer/5/wine/drive_c/Program
Files/TeamViewer/Version5/TeamViewer.exe'" You must also change the default file
context files on the system in order to preserve them even on a full relabel.
"semanage fcontext -a -t textrel_shlib_t
'/opt/teamviewer/teamviewer/5/wine/drive_c/Program.Files/TeamViewer/Version5/TeamViewer.exe'"

Fix Command:

chcon -t textrel_shlib_t '/opt/teamviewer/teamviewer/5/wine/drive_c/Program
Files/TeamViewer/Version5/TeamViewer.exe'

Are you running F12 or F13?

Just set the allow_execmod boolean and it will work.

# setsebool -P allow_execmod 1
Comment 2 Onuralp SEZER 2010-05-11 11:24:20 EDT
I'm using Fedora 12 and thanks
I'm trying now ..
Comment 3 Onuralp SEZER 2010-05-11 11:30:00 EDT
And May I asking something about using yum sometime it's stop downloading and I see 

Example : 



(10/56) : xxxx.rpm (%20) 45% [====         ] 0 B/s | 20 MB    438534594759:00 ETA

Like that 

Why did it do like that sometime ? 

Thanks you working for Team Viewer Problem

Comment 5 Daniel Walsh 2010-05-11 13:35:51 EDT
I think this indicates a loss of network connectivity.  I usually just stop and restart the yum.
Comment 6 Onuralp SEZER 2010-05-11 14:22:56 EDT
